Models

A variant of the Apple II with a different BASIC in ROM was marketed as the Apple II Plus, of which there were a couple of regional variants the Apple II europlus and Apple II J Plus. A new model with expanded capabilities including lower case and better support for 80 columns arrived in 1983 as the Apple IIe. A couple of minor revisions followed before the introduction of the Apple //e Platinum in 1987 which added a numeric keypad and came with the extended 80-column card preinstalled to provide 128k RAM and Double Hi-res graphics.

Music and Sound

The machine has a simple speaker toggle output which programmers have used with tight code to do amazing things with 1-bit resolution. The machine has 7 expansion slots and many sound cards were created for various applications that interface via an expansion slot. The sound card with most support in games was the Mockingboard which provided one or two AY-3-8910 with 3/6 voices.
